How to Build Bench Seats on a Wooden Deck
You can add extra seating to your deck by building bench seats. Bench seats can be moved around the deck to accommodate your different outdoor entertaining needs. The bench consists of a few basic parts, including a seat, legs and a cross support that runs between the legs underneath the seat board. The dimensions of the bench seat can be adapted to your specific needs. Finish your benches with paint or stain to match your deck.
Place the two 2-inch by 12-inch by 16-inch boards parallel to each other and approximately 33 inches apart from the inside edges, with the 2-inch by 12-inch ends flat on the work surface. These are the bench seat legs.
Position the 2-inch by 12-inch by 36-inch board across the top 2-inch by 12-inch ends of the legs. This is the seat board. The outside of the legs should be flush with the ends of the seat board.
Drive four evenly spaced flush-trim wood screws through the top of the seat board into the ends of the legs at each joint, using a screw gun.
Center the 2-inch by 6-inch by 33-inch board between the legs so that the 2-inch by 33-inch edge is flush with the bottom of the seat board and the 2-inch by 6-inch ends are located against the inside of the legs. This is the cross support board.
Drive two evenly spaced flush-trim wood screws through the outside of the leg boards into the ends of the cross support board.
Apply a matching wood finish to the bench seat assembly with a poly brush. Allow the finish to dry at least four hours before handling and 72 hours before heavy use.
